The time is pre World War II that looks like Europe in an imaginary world. A large scale war abrupts and bloody battles are taking place through out the world. Eylstadt is a small country without a strong military force or natural resources. Finé who is the crown queen of Eylstadt decides to use a secret weapon against larger countries which was unheard of at that time to battle against larger countries. The secret weapon was using a witch named Izetta and her magical force to fight the war. Izetta is young (same age as Finé) and the last surviving witch with burning red hair.
